When Under Armour introduced The Original Boxerjock boxer briefs, it took performance wear to a whole new level. This underwear is built from UA’s smooth, sleek HeatGear® fabric for the best performance. The signature Moisture Transport System keeps you cool, the 4-Way Stretch keeps you moving, and the Anti-Odor technology keeps you fresh. Forget your old boxer briefs that bunch up, wear out, or lose shape. The Original Boxerjock 6 Inch underwear stretches, recovers, and fits exactly how you want it to.
